Business-Applied Statistical Results

To address the need for managing regulatory risks and optimizing commercial offerings, I executed Stress Testing and BUST (Bottom-Up Stress Test) for SUGEF. My primary role involved projecting key macroeconomic variables—such as inflation, interest rates, and exchange rates—where I successfully synthesized statistical results with senior management’s expert judgment. This balance ensured that projections were not merely figures, but validated scenarios accepted by the business for critical decision-making.

Rather than providing “black box” models, I delivered transparent tools that enabled managers to clearly identify the right products for each client. By automating these reports and engineering high-value variables through Machine Learning, I transformed the Data Warehouse into a solutions engine that aligns technical rigor with the organization’s strategic objectives.

Measurement Strategist

Transforming Judicial Service Perception into High-Impact Decisions

The Judiciary of Costa Rica faced a critical information gap: a lack of specific data regarding quality perception within the Judicial Auxiliary sector, which hindered decision-making aligned with the Institutional Strategic Plan. To address this challenge, I led the methodological and technical design of a research project focused on capturing the voice of the external user (citizens). My intervention centered on creating a robust measurement instrument grounded in ten key quality factors—such as reliability, responsiveness, and assurance—ensuring the technical traceability required to evaluate sensitive services like those of the Public Prosecutor’s Office and the Judicial Investigation Department (OIJ).

As a direct result, I developed a replicable methodological framework, including a specialized sampling design and multivariate analysis tools for critical data tabulation. This project not only provided the first authentic diagnosis of perceived service quality but also delivered a strategic asset to the Service Comptroller’s Office to optimize public management and strengthen the social legitimacy of the justice system.

District Data Analysis and Validation for the 2022 Census

Faced with the complexity of the 2022 National Census database and the need for high-quality information for public policy, I led the technical analysis and validation for all 487 districts in Costa Rica. Leveraging R, I developed a rigorous methodology to audit population structure and coverage, identifying critical patterns in unvisited households and calculating precise sample sizes for areas with low representativeness. My intervention was key to bolstering data integrity by classifying districts by complexity level and validating statistical imputation methods.

This technical effort resulted in the delivery of five strategic outputs that ensured the census information was viable for timely disclosure. I successfully transformed raw data into a validated, reliable structure, providing INEC and UNFPA with a solid foundation for national decision-making. My management not only filled a specialized technical gap but also guaranteed that key indicators for omission and coverage met international statistical quality standards.
